Valid 120007Z - 120100Z

The severe weather threat for Tornado Watch 213 continues.

SUMMARY...The supercell tornado threat is increasing and likely
peaking in the next one to two hours for parts of the southern OKC
metro.

DISCUSSION...After several storm mergers in Grady County, latest
KTLX radar imagery shows a couple consolidating supercell structures
with more-organized mesocyclones in Canadian and Grady Counties. The
near-storm environment is becoming increasingly favorable for
sustained supercells, with expanding clockwise-turning hodographs
(around 150 m2/s2 0-1km SRH from KTLX VAD and increasing) and lower
70s boundary-layer dewpoints. Given slightly larger supercell
structures moving into this environment, the supercell tornado risk
is increasing and likely peaking in the next hour or two.
